To: emacs-orgmode
I need help to be able to use org-babel functionality.
I use emacs 22.3.1 in windows XP and org-mode 6.34.
I have the following instructions in .emacs
(require 'org-install)
(require 'org-plot)
(require 'org-babel-init)
(require 'org-babel-R) ;; requires R and ess-mode
(require 'org-babel-python) ;; requires python, and python-mode
(require 'org-babel-ditaa)
ESS module is loaded before :
(load "~/emacs/emacs-22.3/site-lisp/ess-5.7.1/lisp/ess-site")
I don't manage to get any output with R Software.
Below you will find test I have done :
#+srcname:trial
#+begin_src sh
echo output
#+end_src
#+results: trial
: output
#+srcname:trial
#+begin_src R
c(4,5,6,7,8,9)
#+end_src
I manage to have shell output, but when I tried R procedure,
I have the following output in *Messages* buffer
executing R source code block...
Syntaxe du nom de fichier, de répertoire ou de volume incorrecte.
Source block produced no output
I have a look on temporary directory and I have the folllowing
file :
R-in-functional-results4452lyl
Inside the following source code :
main <- function ()
{
c(4,5,6,7,8,9)
}
write.table(main(), file="c:/Temp/emacs/tmp/R-out-functional-results4452y8r",
sep="\t", na="nil",row.names=FALSE, col.names=FALSE, quote=FALSE)
The file R-out-functional-results4452y8r exists but is empty.
What I miss to make it work ?
Regards

It requires that the emacs function shell-command can use the string "R" to invoke an R process, i.e. the R installation and the shell path must be such that this is the case. Seeing as you have ESS installed, how about using session-based evaluation? This means that org-babel uses an interactive R session running under the control of ESS. In general it is a better way to work with R in org-babel. It is described in the section "Session-based Evaluation" in http://orgmode.org/worg/org-contrib/babel/intro.php and also in the reference manual: http://orgmode.org/worg/org-contrib/babel/reference.php#header-argument-session basically you just set the :session header argument, e.g. #+srcname:trial #+begin_src R :session org-babel-R-session c(4,5,6,7,8,9) #+end_src Have a look here to see the different methods you can use to make this the default (without having to explicitly set the header arg each time) http://orgmode.org/worg/org-contrib/babel/reference.php#sec-3.1 Dan > > I have a look on temporary directory and I have the folllowing > file : > > R-in-functional-results4452lyl > > Inside the following source code : > > main <- function () > { > > c(4,5,6,7,8,9) > > > } > write.table(main(), file="c:/Temp/emacs/tmp/R-out-functional-results4452y8r", > sep="\t", na="nil",row.names=FALSE, col.names=FALSE, quote=FALSE) > > > The file R-out-functional-results4452y8r exists but is empty. > What I miss to make it work ? > > Regards > > > > _______________________________________________ > Emacs-orgmode mailing list > Please use `Reply All' to send replies to the list. > Emacs-orgmode@gnu.org > http://lists.gnu.org/mailman/listinfo/emacs-orgmode ^ permalink raw reply [flat|nested] 12+ messages in thread

Thanks Seb, That's really helpful. I'm really ignorant about this Windows stuff. So let me get the basics straight: is it the case that, if a user does *not* have a UNIX emulation environment installed under Windows (e.g. cygwin, msys, mingw?) then there is no way that org-babel external shell evaluation is going to work? Or does that statement need to be qualified according to language (R, shell, ruby, ...)? I.e., when a Windows user just has emacs and the native windows/dos shell, are these things just not going to work?

I.e., when a Windows user just has emacs and the native windows/dos > shell, are these things just not going to work? I have to be honest. I will give more impressions than facts, for the simple reason that Cygwin is well implanted in my Windows, and that for more than 10 years now: I began using Emacs in 1999, and have Cygwin bundled with it since then (as Windows is pretty useless without a better shell than `cmd.exe'). So, trying to answer your question, I would split it in two parts: - calling scripts, - calling applications with some data or description. First case: script written for the shell. Without cygwin, your interpreter is `cmd.exe', so pretty limited. And, here, we come back to one question I had some weeks ago about which interpreter is chosen when executing the snippet: bash, Zsh, etc. Same problem here, with a third possible command interpreter. Second case: "applications" like R, ditaa, etc. There, I don't see any problem for calling them with some data to feed them. The only real condition is that the program must be found in the PATH (or the full path to the executable has to be given). Am I answering you in the intended way? Do you want me to make some tests? Don't hesitate... Best regards, Seb -- Sébastien Vauban _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.

I would like to add something which we had to learn the hard way when working on a platform-independent project with a commandline-interface: the native commandline in MS Windows (cmd.exe) can only digest input with significantly fewer characters than the usual shells in Linux and Solaris - and then you get really strange and unhelpful error messages. The number of characters for Windows XP is 8191 characters, for older systems (Windows 2000) it is about 2000 characters. This was a showstopper-class problem for us (we worked around this by putting all previous commandline arguments into an optional parameter file), much later we found an official Microsoft article on this: http://support.microsoft.com/kb/830473/EN-US Warm regards, Stefan -- Dr. Stefan Vollmar, Dipl.-Phys.
